Application 'July 22, 1ssaser'iaimiassisri This-inventionrelates =to lamp guards and particularly -to lamp guards which are detachably connected to a rubber handle member. 7 The primaryobject of the present invention is the .-provision ofa lamp guard having asplit collar, therebeing a clamping member having cooperative engagement with the split collar to clamp the split collar-in position on a handle guard. I

Another object of the'invention is the provision of a lamp guard: having new and improved means for clampingly supporting the guard to a handle by the manipulation of a pivotally mounted-member, which causes a split collar on the lamp guard to'belocked or unlocked into .position.

Aiurther object of the invention is the provision of -a lamp guard having new and improved means f'orfper-mitting theguardto be quickly and -readily opened fortheinsertion or removal of a lamp, the guard also being adapted to be readily and quickly closed, the'meansfor opening and closing the guardconstituting a clamping member cooperating with a split ring or collar.

Numerous other objects and advantages will be apparent throughout the progress of the following specification.

The accompanying drawing illustrates a selected embodiment of the invention, and. the views therein are as follows:

"Fig.5 is a view similar to Figs. 3 and 4, showing the clamping mechanism in full unlocked'position-to have the guard spread apart; and

Fig. 6 is a detail sectional view on the'line 66.o'f Figjl.

Theparticular lamp guard construction he'rei'n shown for the purpose of illustratingthe invention comprises a lampguard Ill made up of a plurality of vertical wires I l and circular transverse'horizontal wires l2, the horizontal wires being split at opposite sides, at the point indicated at l3,Fig."1. The vertical Wire's terminate in a bottom splitc'ollar M, "which is 'formedof two relatively or substantially circular semicylindrical parts l andlfi. The upper ends of the vertical wires ll extend through holes provided in a disk I! and "are bent inwardly into .lockingengagement therewith, as indicated at 18, Figs. 1 and '2. Ahookfipasses through the center of the disk I! and is fixedly or "swivelly connected thereto 50 as to permit the guard to :be himgin place. :ihe guard I0 is adaptedto be-locked to -a handle guard'zfl, which is preferably made of resilient, flexible rubber-like material. The guard m has a longitudinal bore "to receive a cable, carrying electrical conductors which make electrical contact to a socket 21 arranged inside oi the upper enlarged portion of the handleguard ZD. A lamp'is adapted to screw into-thesocket 2|, and the guard in extends about the-lamp toprotectthe lamp from breakage.

The vertical wires II have some free movement with respect to the disk H, and therefore the guard may-bespread apart in a hinge-like fashion, the hinge being formed about the vertical wires Hpassing throughthe holes in the disk I1, and inasmuch as the horizontal wires l2 are split cn both sides, as indicated at l3, one part of the guard ma'y be swingingly or pivotally inoved-toward and-away from the other part so as to permit the insertion of a lamp withi'nthe guard it. Heretofore, various means have been .provided for-locking the collar l4 about the han- --dleguard 20,-the handle guard 26 being provided with an annular recess 22 "to receive the collar, and when the collar is locked in place, it will squeeze the rupb'er body and lock the socket or "connector in place.

The present invention contemplates the provision of "new and improvedmeans for permitting ready and-quick action for unlocking the collar i5, -so as topermit one section of the guard II] to be swung away from the otherpart of the guard for ready-insertion of a lamp in the handle -20 or-removal thereof. The means for accom- ..plishing-quick-andready attachment and detach- -ment of the two parts [5 and I6 of the collar comprises a clamping element 23 so constructed "and -arranged that the mere movement of one part will cause the detachment of the collar, and no tools areneeded to causesuch attachment and detachment. Ij-heclamp 23 may comprise any kind-of'means fordrawing the two sections toagether and clamping them in position to lock -the=parts together andto unclamp the two parts -by the mere manipulation of a single element. The clamp herein shown for accomplishing this result comprises two .pivotally connected members 4M and 25, the member 24 being pivotally connected to the collar section l 5, and'the member 25 being -ipivotal-ly connected to the member -24. The-member 24 :comprises a single .pieceo'f wire of general semi-cylindrical shape, having oppositely disposed upwardly extending legs 26 which-are hent inwardly, as indicated at 21, Figs. 6 to '5, and extend into openings or'holes 28, Fig. l ,.-provided in the collar section linear the ends -thereoi-.; 'Ifhe member 25 is relatively semicircular --and is ;bent at 29 to provide inwardly extending l egs -38, which -are received in eyes '3"! =-formed*-in {the --member 24. {Ihe'se eyes -3i are formed -'-in the semi-cylindrical wire me'mber 2'4 by merely bending the wire in the form of a loop, as shown.

The outer end of the member 25 is adapted to be held in locked position by a keeper 32. This Ikeeper 32 may comprise a groove 33 formed on the upper outside edge of the member I6 substantially midway between the free ends thereof.

Instead of providing a groove 33, Fig. 3, an outstanding pin 34 may be employed so as to hold the member 25 in proper position, Figs. land-5.

In actual use, the guard I0 and its cooperating clamping member 23 is in the position shown in Figs. 1 and 2, with the member 24 in its uppermost position lying against the upper guard wires I I. When it is desired to unlock the guard ID, the member 24 is moved downwardly to the respective positions shown in Figs. 3, 4 and 5. As the clamping member 24 is moved downwardly to the position shown in Fig. 3, the parts will be in unlocked position, except the member 25 will still be locked Or received in its keeper 3234. Continued downward movement of the member 24 will release the member 25 from the keeper 32, as shown in Fig. 4, at which time the member 24 is free to be moved downwardly, as shown in Fig. 5, whereby the clamp 23 is completely disconnected or disassociated from the part I6. One-half of the guard Ill is therefore free to be swung outwardly from the other part of the guard I0, providing ample room for the insertion or removal of a lamp globe, as shown in Fig. 5. When it is desired to reconnect the parts, the part 25 of the clamping member 23 is moved upwardly so that it lies above its keeper 32, as

shown in Fig. 4. Then when the member 24 is moved upwardly, the collar I6 will be drawn toward the collar section I5, tightly squeezing the rubber about the groove 22. Then as the part 24 is moved home to the position shown in Fig. 1, the eye 3! will be above its pivotal connection where the legs 25 enter the openings 28 and cause a snap clamping action, thereby looking the clamp in position, as well as tightly looking the two sections of the collar together, causing the guard ID to assume its normal position, as shown in Figs. 1 and 2. Therefore, when the clamp is in its home or locked position, as shown in Figs. 1 and 2, the clamp will be above its straight line locking connection, and the pull is such that the upper end of the member 24 will be pulled up against the guard I0. Also, when the clamp is opened and the part 24 is pulled down beyond the straight line clamping action, the part 24 will tend to snap downwardly in an opposite direction, causing the unlocking of the device. If desired, the member 24 may be provided with a bent or leg portion 35 so as to provide a rest for the guard when it is lying on its side, and therefore preventing the guard from rolling, there being a leg 35 on each side of the member 24 to provide these oppositely disposed legs which act as rests or supports. The device, when lying down, will therefore rest on the legs 35 and'on an upper horizontal wire l2.

configuration to perform the function intended.

The guard is relatively inexpensive to manufacture, and it can be readily and quickly assembled.

Changes may be made in the form, construction and arrangement of the parts without departing from the spirit of the invention or sacrificing any of its advantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claims.
